SUMMARY: Netra T1, serial console unable to use input device]

Thank you very much for your support, some respondes and ideas like the
use STIOP+N a keyboard this could help, but some of the netras dont
have a keyboard port and the one who have its USB an I remenber reading
someplace that the interrupt level for a USB
is one of the latest and these sequences are not recognized.
The jackpot is for "Petersen, Dwight" <Dwight_Petersen@intuit.com>
which make the following statement.
netras are different. I have little adapters with my netras. I think
sun
ships them with the netras.
If you don't have the adapters, and you do have a Cisco rollover cable
(that
is slightly different from a crossover cable, but I'm not sure what the
difference is) a cisco rollover cable between a laptop (with terminal
software) and the netra will allow you to talk to your netras.
This is absolutly correct, A Sun service eng. came and use a special
adapter with an RJ45 cable, and it worked
but what I cant explain is why we use this cables a long time (even for
reconfiguring and installiing the netras ) and
suddenly it worked no more, I someone would like the electrical
configuration or the sun part number i would
please tellme.
The original question is posted below !

Hello managers, I have a huge problem that I dont know what can be
causing it.
I have 5 netras t1 ( 2 x 105 ) and the others with no aditional info.
yesterday 2 of those 5, we change the network configuration of the
interfaces along with two 220R.
But here is where the weird stuff begins.
after changing the config. and the init 6, the serial input is completly
dead, the OBP values where changed
cause it tries to boot from the net.
I use an ultra 5 as the serial console, using the serial cable provided
by sun ( RJ45 -> DB25 ) but nothing seems to work.
I CAN'T enter ANYTHING on the input, no matter if it is on the LOM,
OBP I even create a boot server to see
if Solaris could help, but nothing the machines refuses to accept input,
it simply doesnt work.
I see al the LOM output , and all the POST output I even can se how
solaris can be ready to install with the boot server.
but nothing, I tried 3 different cables ( which I already used for
installing this machines ).
I tried with another two machines to tried to connect, a Windows with
hypertermial , a Linux with minicom , and the first Solaris with tip.
all the config was always 9600,8,N,1
I dont know what can be happening , I presume that the input-device
OBP variable was changed but I can really can asure
cause I input any commands , Does anyone knows how to reset the default
values of this machine, Or anyother hint
suggestion Is extremely welcome.
Thanks I will Summarize !
